When you wish to learn Electronics, first a short study of
Physics is essential, secondly some Electronics theory. Then
build simple and small electronic projects to learn
Practical Electronics while working with Educational Hobby
Circuits. Lastly to make your own product designs, a
fundamental knowledge of Analog and Digital Electronics is
the foundation for your next steps into Engineering a
Design.

Applications and Components

The basic building blocks for most circuits are Chips or
ICs. You can acquire considerable knowledge by studying
Application notes. Then you would want to use a
Microprocessor or Build Microcontroller Projects. The
Specifications and Behavior of Passive Components like
inductors, capacitors and Resistors; Discrete
Semiconductors; Power Devices and RF Components have
to be understood well, in order to design sturdy Industrial
Grade Designs.

Advanced Engineering

The Technology related to the equipment used for Testing,
Troubleshooting and Calibration is called Test &
Measurement, Here we use Test Instruments like Oscilloscopes
and Digital Multimeters. Medical Electronics and Military
Designs require more meticulous, robust and dedicated
designs with higher reliability and accuracy. In Medical
electronics product safety is vital, Consumer products
should be affordable without compromising Human Safety
factors.

Then you need to look into Usability or Ergonomics, which is
a science that helps us develop practical and cost-effective
products, which have an optimum Man-Machine Interface. EMI,
ESD, RFI are other important aspects that deals with
Electromagnetic, Electrostatic and RF; Noise and
Interference; in the Stable performance of products in Real
World Harsh Environments or the Reliable Transmission of
data. Lastly Computing and Communication makes products more
versatile in any application. EDA, Technical Computing and
Systems Engineering helps creating products and complete
process solutions.

Industrial Automation and
Process Control

Automation and Control is the predecessor of Robotics and
Mechatronics.

A Control system is made of Sensors sending acquired data to
a Controller which operates Actuators to manage the process
in Real Time. Starting from a Bimetal Thermostat to a SCADA,
the controller has grown from mechanical -- electrical --
analog -- digital devices to microcontroller-computer based
equipment.

Both in Control Systems and Robotics the Collaboration
between Robots or Control Units, leads to the development of
wireless network of Interactive, Intelligent and Distributed
Self Governing Systems. The outcome is Web Process
Automation, Web Applications based Solutions in Monitoring,
Analyzing and Configuring these Sophisticated Networked
Systems.
